WARNING
In
INOP Only
mode, no fetal/maternal patient alarms are enabled or indicated.
The alarm status area for yellow and red alarms shows the INOP only indication in conjunction with
the "Alarms Off" symbol. No alarm limits or alarm off icons are displayed. No fetal/maternal patient
alarm settings are available in the setup menus.
Visual Alarm Indicators
Alarm message: An alarm message appears in the alarm status area on the second line at the top of the
screen indicating the source of the alarm. If more than one measurement is in an alarm condition, the
message changes every two seconds, and has an arrow at the side. The background color of the alarm
message matches the alarm priority: red for red alarms, yellow for yellow alarms, and light blue for
INOPs. The asterisk symbols (*) beside the alarm message match the alarm priority: *** for red alarms,
** for yellow alarms. INOPs are displayed without asterisks.
Depending on how your monitor is configured, it may display alarm limit violation messages:
•
in text form, for example
** FHR1 LOW
or
• in numeric form, for example
**FHR1 94<110
, where the second number shows the currently set
alarm limit, and the first number shows the value at which that alarm limit was violated by the
widest margin.
Flashing numeric: The numeric of the measurement in alarm flashes.
Bright alarm limits: If the alarm was triggered by an alarm limit violation, the corresponding alarm limit
on the monitor screen is shown more brightly.
Audible Alarm Indicators
The audible alarm indicators configured for your fetal monitor depend on which alarm standard
applies in your hospital. Audible alarm indicator patterns are repeated until you acknowledge the alarm
by switching it off or pausing it, or until the alarm condition ceases (if audible alarm indication is set to
non-latching).
WARNING
Do not rely exclusively on the audible alarm system for fetal monitoring. Adjustment of alarm volume
to a low level or off during monitoring may result in a dangerous situation. Remember that the most
reliable method of fetal monitoring combines close personal surveillance with correct operation of
monitoring equipment.
Alarm Tone Configuration
The audible alarm indicators of your monitor are configurable. In the monitor's Configuration Mode,
you can change the alarm sound to suit the different alarm standards valid in different countries.
Standard Philips Alarms
• Red alarms: A high pitched sound is repeated once a second.
